NUSIL: Fluorosilicone Dispersion

NuSil Technology LLC has added MED-6655, a fluorosilicone
dispersion, to its line of dispersions for healthcare applications. MED-6655 is
a one-part, 100 mol% fluorosilicone adhesive/sealant dispersed in tert-butyl
acetate.

The dispersion comprises 60%
solids with a medium durometer. Because it is a room-temperature vulcanizing
(RTV) material, MED-6655 is ideal for spraying and dip-coating processes, as
well as sealing and bonding applications.
For applications in which a standard dimethyl system may be
compromised and swell, MED-6655 can be used in its place to provide resilience
to various solvents and alcohols. In addition, the dispersion has low gas and
moisture permeability compared to a standard dimethyl system.

“MED-6655 can be used for a variety of applications because it has
less of a tendency to swell when exposed to dimethyl silicone fluids or other
solvent-based environments, including alcohols,” said Brian Reilly, product director
ofHealthcare Materials for NuSil. “It also adheres well to a variety of
substrates.”

The dispersion can be considered for long-term implant
applications of 30 days or more, according to the company. A variation of
MED-6655 is also available for external devices for short-term implant
applications of 29 days or less. Master Access File and biological testing will
be filed with the U.S. FDA.

Events

The presentations will be focused on presenting recent research and results from leaders in the photo polymerizations field. Each speaker will be asked to present their recent results and critical achievements that have resulted from their research or those that would aid them in product development.
